Outstanding quality, commitment to repairability and a great price

This light is one of the rare products that seriously impresses me. The build quality is excellent with a metal case. The light is held together using hex screws and is designed to be opened by the user. Serfas sells replacement parts for the lights such as handle bar mounts and replacement batteries. The light is seriously bright and lights up the whole road perfectly. I absolutely recommend getting this light. Its the last one you will ever need to buy.

Quite bright and easy to attatch but seems to have serious quality control issues.

A friend and I both purchased these lights from different sources. They worked fine for a while but after a few months of use we both had them fail. For me the rear light still works fine but the front light fails to hold a charge. A few days of sitting unused will cause them to drop from fully charged to empty. My friend had similar issues with them not turning on anymore. Would avoid this brand in the future.

Well priced and minimal but lacking in documentation

The GnuBee is a network attached storage device supporting up to 6 sata drives and runs linux with full user control given. I ordered one and it arrived fairly quick considering it was shipped from far away. Assembly is really simple. You just have to attach the side plates to the pcb. When I ordered I couldn’t work out what the USB UART cable was for and did not get one. I later found out that this cable is super important for installing an OS on the GnuBee. I sourced a cable from ebay which worked but this prevented me from using the device for a month.

I found the documentation available online to be really lacking and it took a lot of investigating to work out how to get something running on the device but there is a fairly active community on the mailing list which was a huge help. Once I got debian installed and working I was able to use the familiar linux tools to set everything up to my liking. I wanted to run a speed test on the device but I wasn’t able to find a fair way to do it. I network mounted the device via SSH and I was getting 4MB/s over the local network but multiple posts online have pointed out that SSH is inefficient for large data transfers. I was not able to find a faster way to network mount that maintained the security of SSH.

Overall I think the hardware is designed right and once you get it installed and set up its really quite easy to manage. Actually getting it to that point took a while but this can all be fixed later via documentation improvements.
